also when in pause, Q-FRAME would usually go like this
74 73 72..03 02 01 [00] 74 73...
but in some cases ther's 2 F=00 frames
74 73 72..03 02 01 [00 00] 74 73
so EAC would for some reason excluded those additional 00 frames from math
and determine pause to be smaller than it is (TJCD9002 Super Albatross: T2:EAC=2.73/should be 3.00)
i'll post this on EAC forum, maybe they can fix it or explain algorithms, maybe there is a reason but unlikely

Re: would you consider adding an PC Engine CD, please? (55 replies, posted in General discussion)
sometimes EAC would get a strange gap layout again. all close to 0 except for those wraping data tracks. for example TJCD0007 Death Bringer:
Track|Gap
01 |02:00
02 |03:00 <=data
03 |02:00
04 |00:00
05 |00:02
06 |00:01
07 |00:02
08 |00:01
09 |00:00
10 |00:01
11 |00:01
12 |00:00
....
and so this is what's going on in subchannel:

so there are no gaps. INDEX is never 0; MSF never count back. only thing different is relation between subchannel track index and TOC. size of pause is presumed depending on this difference alone. Tracks 4, 9: hit on TOC - pause =0; Tracks 8,10 differ by 1 frame - pause =01; Tracks 5, 7 kick in with a 2 frame delay - pause =02; Tracks 6,11 should have been 02, applying this math, but ADRESS=2 type frame shifts them to 01.
so there is no reason for gaps, it's only a strange mastering of cd. i'll go instead for a cdrwin gap layout in such cases: audio2audio=00
*edit: i forgot about numbering difference. it's last frame marked not first*

yes, 1st track's crc match with TJCD1018
so i think it should be ok

thanks, that's what i thought 
i saw that topic on sor board, but relative cues is not much use i guess unless you have files split the same way

Re: would you consider adding an PC Engine CD, please? (55 replies, posted in General discussion)
umm, it does not work for me
Disc with ID "2030" doesn't exist.
also there is no PCE section on drop down, but when i go to
http://redump.org/discs/system/pce/
it says: No discs found.

I added my first PCE dump
Things to note:
1) cuesheet is manually edited based on gaps reported by EAC: since the CD layout isn't standard at all, EAC doesn't automatically list all tracks in the .cue, but only the first audio track, while PerfectRip gives an error on last data track, so it doesn't save the .cue
2) I dumped both data tracks with IsoBuster: I resized track02 by 2:00, which is track03 pregap
3) both data tracks have a 2.74 (526848 bytes) pregap I attached using psxt001z, because IsoBuster doesn't dump pregap before data tracks: this way the total sector count of the dump is right and matches the actual CD
yeah, the same here, everything's as you said
and cdrwin fail too on full scan, but on quick gaps differ a bit 
and cdmage won't open
offset: -1341

to verify a crc of an existing dataonly psx cd all you'd do is click on Extract Track 01/Extract RAW Data (2352...). but if cd is damaged i think IsoBuster should give you a warning. could you please scan this image with psxt001z --fix or --scan or CDMage, maybe it is different somehow after all... or if you get no warnings in IsoBuster but do when scanning an image, it could be that this drive is not good for ripping.

Topic: .CUEs with absolute time (2 replies, posted in General discussion)
maybe it is possible to create a script that would generate .CUEs with absolute time from track offsets in .db. so people who do have single cd image with multiple tracks could use it. and since dynamic, it would change according if changes are made to cd layout in db.

i'd get 00 sometimes on audio sectors but never on data so far. but our drives are different. maybe ther's a firmware update?

Re: a bit more on odd GAPs (13 replies, posted in General discussion)
i think i can. i use 'px_d8' that Vigi posted link to and i give it an LBA of the data track and even on first and last data tracks result would always be the same. so i think it's ok. it is huge negative most often, you're right.

i also made a little script that would do a math. maybe you can find it useful. it's on awk.
http://www.mediafire.com/?4nzfhyccym1
so you can place everything in directory where px_d8.exe is and call offset.bat like this
offset DRIVE LBA DRIVECORRECTION
e.g.
offset h 3600 30
it will do 3 readings on different sectors then and return Absolute offset for DB and relative ones for all my 3 drives
to configure your drives change D1,D2 and D3 in offset.awk to your EAC offsets

Re: a bit more on odd GAPs (13 replies, posted in General discussion)
to be honest i don't know. EAC is wrong, but defined dumping relies heavy on EAC. if you keep them that way, more people will be able to compare and verify with DB. it's most importan't i guess.
data shoudn't change, so it must be possible to correct gaps by moving corresponding amount of sectors from track to track. in this case 2352 bytes from the beginning of the track following gap to the end of the one before.

Topic: a bit more on odd GAPs (13 replies, posted in General discussion)
i think i've found out why EAC would return a rather strange GAP layout sometimes.
it's only a 1 special case, but it happens time to time.
when uncertain you can use Subcode Analyzer to take look at subchannel by yourself.
and so you will see something like this:

(last sector for this track from TOC is 76812)
TNO increase; INDEX=0; MSF - resets and counts back
(since it's 74 this time, we can assume result will be a multiple of 75)
and afterwards: INDEX=1; MSF - reset again and count forward
Q=76813-76663=150=2 sec;
this is i think what EAC would do on a 'Detection method A'
'Detection method B' appears to be something less raw since it works on drive that
can't do a full subchannel read and will return correct gaps for 1Data+1Audio CDs
on the other drives it would return a rather random numbers but somewhere close to 2"
so maybe it's just some command for a drive to get pauses and is like outdated by now.
i don't know what 'C' is
P=76814-76664=150=2sec
P goes with a little offset from Q but most of the time yields the same result
but sometimes it would differ, like on older Mega CD games P usually is 186 when Q=150
i guess for this or some other reason it is not used in the most soft at all i think.

ther's ADRESS=2 sector right on boundary, actually it shadows last frame before Pause
(how can you know it's not shadowing a part of a Pause? you can do calc on P.
compared to other tracks, it should increase if it would. it does not in this case)
but EAC counts it as 1st sector of Pause and thus GAP increase by 1 frame
why it is there i don't know, i think it belongs to Audio CD standard and should not be
on mixed mode at all. though it is. on Mega CD and Saturn - every 98th frame.
CDRWin can get GAPs correct in this case.

Re: would you consider adding an PC Engine CD, please? (55 replies, posted in General discussion)
also in usa mega cd disc format specification it says pauses should be >=2sec. and somewhat strange thing is for example with 1st cd: G-6001, spliting tracks by detected gaps cuts data in half but if not detection is used pauses align nicely at the beginning and end of each track. still i think no data is lost, total size of audio tracks differ only by postgap but it's always 00, isn't it? so like if all tracks were put back togeather in img or bin no matter what gaps was full crc would be always the same. only cue differ.

Re: would you consider adding an PC Engine CD, please? (55 replies, posted in General discussion)
yes, i understand your concern, that issue with no gap on 2 tracks, the result would be data lost, ok. but i think it's some eac internals. on psx i would get it correct on 1 drive from 3 and it can be verified with sector viewer and also full cd size would always match so i think it's ok. but what i mean is, i think ther's those all 2sec gaps and one 1.74 and oddities like that on this system but even if it's later proven to be wrong, like all gaps should be even, data would not be lost, only shifted, would it not? so existing dumps could be easy modified should such a need arise. and like 99% info can be verified until then so it's not lost like part of tapes and floppies are now.

both has offset -12, what's a bit unusual for Japan region
AFAICT only difference is that both SM bytes in 11th sector are set to 88 (Data=1;EOF=1)
and EDC/ECC changes accordingly. in every other way it's just like 'Jap EDC'
and also SM bytes in sector following right after system region hasn't got EOR bit set

Re: Offset detection using the D8 read command - Discussion (67 replies, posted in General discussion)
i added log below from i think it was Vagrant Story
i made a little script to do this fast and i would pass to it usually also sector 10 or 100 or so
when it was 31 most of the time but can't say that always
no, i would usually set offset to PR 0 for data cds. did not know of this. but now i rechecked everything and 31 are only for listed games above.
31 is strange. it looks like this change occurs in time around year 2000. firs cd i saw with it was Tales of Eternia, i could determine because it has audio tracks. but it was the only one then and i was not sure and did not submit it.
